It's great to get all this information from different sources ... all these numbers are designed to one purpose - get a buyer into the dealer.
But the bottom line usually: If you get a price that suits you or fits your wallet, you'll buy a truck. If you don't, then you won't.
What is a truck worth to you? Figure that out, and you'll be a happy camper with a new truck.
Despite a lot of probably mostly true stories on here, most dealers are honest, and will not deceive the public. Otherwise, they won't stay in business long.
